JUMPERS

The mainboard provides jumpers for setting some mainboard functions. This

section will explain how to change the settings of the mainboard functions

using the jumpers.

Clear CMOS: CLEAR_CMOS

The onboard CMOS RAM stores system configuration data and has an

onboard battery power supply. The long-life battery has a lifetime of at least

5 years. If you want to clear the system configuration data from the CMOS

RAM, use the CLEAR_CMOS (Clear CMOS jumper). You can clear the CMOS by

shorting 1-2 pin while the system is off. Then return it to the 2-3 pin position.

Shorting the jumper while the system is on will damage the mainboard.

RCA Video or S/PDIF Select: SPDIF_SEL

Users can select either RCA Video or S/PDIF as the enabled function on the

dual-purpose port. For RCA, short pins 1 and 2 (default). For SPDIF, short

pins 3 and 4.
